Offshore Sydney Basin – Direct Hydrocarbon Indicators

DHI have been initially observed on seismic line B4-15 along the main structural trend and are adjacent to the previously identified Baleen Prospect. The features are typically prime indicators for the occurrence of hydrocarbons

Confirms the existence of three core seismic attribute analyses (e.g. multiple collaborative measurements) in the deeper part of the PEP11 seismic section

•high amplitude bright spot reflections

•attenuation of high frequencies in instantaneous frequency plots

•bright spot features in Root Mean Squared amplitude plots

Offshore Sydney Basin – Direct Hydrocarbon Indicators

Figure 69: Display of Line B4-15. The continuity of high amplitude reflector has been mapped.

“Strong energy reflections present on seismic section can be associated with

major lithologic changes as well as hydrocarbon accumulations.”

Figure 70: Reflection Strength plot of the high amplitude reflector

“Gas reservoirs, in particular, appear as high amplitude “bright

spot” reflections.”

Offshore Sydney Basin – Direct Hydrocarbon Indicators

Figure 72: Instantaneous frequency plot for the high amplitude reflector. It is showing low frequency anomaly.

“Instantaneous frequency content is of interest in that high frequencies are attenuated by gas and condensate

reservoirs.”

Figure 74: RMS of seismic amplitude over the area of Line B4-15, where high amplitude

reflector is mapped.

“The Root Mean Square (RMS) amplitude … may be used to map direct

hydrocarbon indicators in a zone.”“The RMS of seismic amplitude for the 700ms window have been calculated.

This indicates a bright spot like feature, which is a prime indicator for the

occurrence of gas.”

B4-16 Preliminary Final PSTM (Zoom)

Data reprocessing from phase 2, 2009 indicates a flat spot on the time processing within structure on line B4-16 which may warrant further investigation.

Area of interest is cmp900 to 1060 (2 kms) at a time of 1500ms and 1700ms.

Note polarity of flat spots is opposite to the seafloor indicating a likely soft response.
